Date requests, "xARs", have been submitted for each Core Site. ASTER scenes will be ordered for each of the Core Sites. The acquisition and ordering will be set up to correspond to field work, ETM+ orders, and/or phenology on the site.
The ASTER data acquired for the Core Sites will be stored at EDC DAAC, openly available through ftp (link given in the "Available Data" table for each site).
